Correction to: Bone Res 10.1038/s41413-022-00211-2, published online 22 June 2022

During a re-read of our previously published article¹ in Bone Research, we regrettably found that the use of statistical chart for NOS2-FABP4 positive cells on the right side in figure 1(d), the quantification of NOS2-FABP4 positive cells in figure 3(a), CD31-EMCN positive cells in supplementary figure 2(h) and branch point in supplementary figure 3(d) were inaccurate. Although those statistical charts do not affect the results and conclusion in the article, all the authors agree to correct this negligence by providing correctly drawn figure 1(d), figure 3(a), supplementary figure 2(h) and supplementary figure 3(d), which are presented below, to guarantee the accuracy of the statistics. We sincerely regret and apologize for any inconvenience caused.
